摘要： The present invention concerns a device for collecting solar energy by means of a concentrator (12) of the nonimaging type and a receiver (3) for the transfer of energy by heat exchange with a fluid which operates, independently, a thermodynamic cycle for the exploitation of energy, said concentrator (12) comprising an inlet area (1), an underlying outlet area (2) and an inner space between said inlet area (1) and said outlet area (2); said receiver (3) being positioned under said concentrator (12) and said inner space of the concentrator (12) and said receiver (3) being connected by said outlet area (2), characterised in that said inner space of the concentrator (12) and said receiver (3) are in fluid communication through said outlet area (2), a plurality of solid particles (11) are present inside said receiver (3), and said device for collecting solar energy comprises means (6) apt to take a part of said solid particles (11) from said receiver (3) and to put them from below inside said inner space of said concentrator (12), said solid particles (11) subsequently returning, by gravity, into said receiver (3), passing through said outlet area (2).

摘要： An image processing system generates enhanced synthetic aperture radar (SAR) imagery using a trainer that generates an information model that defines a set of trained data based on correlated classifications of pairs of spatially and/or temporally coincident SAR and optical images, and using a SAR image enhancer that applies a transformation to generate a color image from the SAR image data. Correlated classifications may be based on specific applications. The system may generate or update trained data to be used for classification based on a set of training SAR images and training optical images. The system may assess or determine correlations between the classified SAR and optical image data sets, establishing levels of confidence in such correlations.

摘要： A planar phased array antenna assembly includes a first face sheet with a first plurality of radiating slots for a first frequency band and a second plurality of radiating slots for a second frequency band, a second face sheet, a third face sheet, and a structure interposed between the first and second face sheets with a third plurality of radiating elements at the first frequency band and a fourth plurality of radiating elements at the second frequency band, and a first feed network for the third plurality of radiating elements and a second feed network for the fourth plurality of radiating elements, and the second face sheet interposed between the structure and the third face sheet. The planar phased array antenna assembly may form part of a synthetic aperture radar (SAR) antenna.
